HEADLIGHT DIMMER.

Application filed February 12, 1924. Serial No. 692,448.

T 0 all whom it may concern Be it known that CARL W. C. COOPER, citizen of the United States, residing at Huntington, in the county of Huntington and State of Indiana, has invented certain new and useful Improvements in Headlight Dimmers, of which the following is a specification.

My invention relates to improvements in headlights and more particularly to an attachme'nt for dimming the headlights of vehicles.

The primary object of the invention is to provide an electrically operated curtain movable to cover the lower portion of the lens of the headlight to obstruct the ray of light projected from the lower half of the reflector.

A further object of the invention is to providea curtain wholly mounted within the casing of the headlight to protect it from the weather.

Another object is to provide a device of the above-mentioned character which is simple and durable in construction, reliable in operation, and inexpensive to manufacture.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanyingdrawing forming a part of this specification and in which like numerals are employed, to designate like parts throughout the same,

Figure 1, is a perspective view of a headlight constructed in accordance with my in vention, and,

Figure 2, is a fragmentary vertical sectional view of the same.

In the drawing, wherein for the purpose of illustration I have shown a preferred embodiment of my invention, the numeral 5 designates a casing rounded at the top and square at the bottom, housing the bulb 5 and reflector 9. The front of the casing is equipped with a removable cover 6 heldin position by the pintle pins 7 at each side. The cover is provided with a circular opening covered by the usual lens 8 to permit the emission of light rays cast outwardly, from within the casing, by the reflector 9.

A spring roller 10 is mounted in brackets 11 secured to opposite sides of the casing adj acent the bottom thereof, and below the periphery ofthe lens. A curtain 12 constructed of any non-translucent material is wound on the roller 10 having one endpermanently attached thereto. A stiffening rod 13 extends across the free end of the curtain, its

endsbeing slidably mounted in the'vertical guides 14 at each side of the casing. A metal lug 15 is attached to each end of the Mounted above the lugs 15 and in vertical alinement therewith are a pair of electromagnets16 arranged on a horizontal plane with the center of the lens. Tires 17 lead rod 13 being positioned to the rear thereof.

from the magnets to a battery and switch (not shown), through the medium of which the magnets are energized attracting the lugs 15 which raise the curtain covering the lower half of the lens. To provide for the passage of the curtain an opening 18 is cut through the reflector. When the magnets are de-energized the spring roller will rewind the curtain.

Thus, it is seen when operating the vehicle at night the headlights may be rendered glareless by raising the curtain to cover the lower half of the lens, when approaching pedestrians and vehicles moving in the opposite direction. A

It is to beunderstood that theform of my invention herewith shown and described is to be taken as a preferred example of the same, and that certain changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus fully described my invention, I claim:

1. In combination with a headlight, a roller mounted within said casing, a curtain wound on said roller, lugs carried by said curtain and magnetic means for at-- tracting said lugs to unwind said curtain.

2. In combination with a headlight, a

spring roller mounted in the bottom thereof,
